The production of prompt photons has been studied in the collisions of quasi-real photons at LEP. The OPAL data taken at e+e- centre-of-mass energies between 183 and 209 GeV have been used. The results are sensitive to the quark content of the photon. They are compared to the leading order predictions of PYTHIA.
